Answer:

Let the required number be ' x '

According to the given problem

  • Equation :--- <u>2(x + 5) = 20</u>

Now, by solving for x, we get

2(x + 5) = 20 \\ (x + 5) =  \frac{20}{2}  \\ (x + 5) = 10 \\ x = 10 - 5 \\ \boxed{ x = 5}

  • <u>2(x + 5) = 20</u> is the required equation
  • <u>x</u><u> </u><u>=</u><u> </u><u>5</u> is the required value of x

Graph the line with slope 2 passing through the point (1, -3).
Pepsi [2]

Answer:

2x-5=y

I'm not sure how your graphing tool works so I'll give you five or so coordinates

(-1,-7)

(1,-3)

(0,-5)

(2,-1)

(-2,-9)

Step-by-step explanation:

You first need to write an equation that you can graph

Knowing that the slope is two we can write the following equation

2x+b=y

We also know that when x=1 y=-3

This gives us 2*1+b=-3

which means that 2+b=-3

subtract 2 from both sides to figure out the b=-3

This means that the line you have to graph is 2x-5=y

How should the decimal point in 34.05 be moved to determine the product 34.05 × 10 to the power of 6?
Ray Of Light [21]

Answer:

The decimal point should be moved Six places to the right side because there are Six zeros in 10 to the power of 6.

Step-by-step explanation:

As we have to represent the number in the form of 10^{6} we need to move the decimal Six places towards left because there are Six zeros in 10^{6} i.e. 1000000. For this purpose we will add four zeros to the left of the number.

So the number in the format mentioned in question will look like -

0.00003405 × 10^{6}.

5x+8=3x-6 plz help me asap
Ray Of Light [21]

Answer:

x = -7

Step-by-step explanation:

5x+8=3x-6

Subtract 3x from each side

5x-3x+8=3x-3x-6

2x+8 = -6

Subtract 8 from each side

2x+8-8 = -6-8

2x = -14

Divide by 2

2x/2 = -14/2

x = -7
